Answer:

y = 12

Step-by-step explanation:

Look at the left triangle first. Opposite the 30 degree angle (not shown) is the shortest side, which (according to the sine function) is half the hypotenuse, or 2√3. Then (2√3)² + x² = (4√3)², or

4(3) + x² = 16(3). Thus, x² = 16(3) - 4(3) = 12(3) = 36, and so x = 6. Again using the sine function, we find that x = 2y = 6, so, using the sine function, we find that sin 30° = 6/y. Thus y = 6 / (2/1) = 12 = y

The area of the rectangular floor in Tamara’s room is 9556 square feet. The width of the room is 813 feet. Part A Round each mea

denis23 [38]

Answer:

Area of Tamara room

=9556 square feet

Width

=813 feet

Length= 11.75 feet

Total area= 19794 square feet

480 square feet will not be enough

Step-by-step explanation:

Dimensions of Tamara's room to the nearest whole numbers

Area of Tamara room

=9556 square feet

Width

=813 feet

For the length

Length*width= area

Length= area/width

Length= 9556/813

Length= 11.75

To the nearest whole number = 12 feet

The ceiling is 12 feet high

Let's calculate for the area of the combination

1)Height and width two times

2)Height and length two times

1).area = 12*813

= 9756

Then 9756*2= 19512

2). area= 12*11.75

= 141

Then 141*2= 282

Total area = 282+19512

Total area= 19794

Yet another question.

inna [77]

Answer:

t= 3 years

Step-by-step explanation:

So far we have 2 useful relationships $P_{t}= P_{o} e^{r*t}$ and $P_{t}=2P_{0}$

Now, clearing t

$P_{t}= P_{o} e^{r*t} \\\frac{ P_{t}}{P_{o}} = e^{r*t}\\\frac{2 P_{0}}{P_{o}} = e^{r*t}\\2 = e^{r*t}$

I apply logarithm

$log(2)=r*t\\ t=\frac{log(2)}{r}\\t=\frac{0.3}{0.1} \\ t=3$ years

Done
